Title (EN) PHOSPHORUS-POTASSIUM-NITROGEN-CONTAINING NPK-FERTILIZER AND A METHOD FOR THE PREPARATION OF GRANULATED PHOSPHORUS-POTASSIUM-NITROGEN-CONTAINING NPK-FERTILIZER
(FR) ENGRAIS NPK CONTENANT DU PHOSPHORE, DU POTASSIUM ET DE L'AZOTE ET PROCÉDÉ DE PRÉPARATION D'UN ENGRAIS NPK CONTENANT DU PHOSPHORE, DU POTASSIUM ET DE L'AZOTE GRANULÉ
Abstract:
(EN) The invention relates to a complex nitrogen-phosphorus-potassium NPK-fertilizer, where mass fraction of total nitrogen is from 13-15%, mass fraction of total phosphates, in terms of P2O5, is from 11-15%, mass fraction of potassium, in terms of K2O, is from 7-8%, and also to a method for the preparation of said fertilizer from a solid phosphate salt, being a mixture of fluorapatite Ca5(PO4)3F and dicalcium phosphate CaHPO4nH2O, where n is 0 to 2, with fluorapatite Cas(PO4)3F content from 27% to 99%, using various potassium salts, in particular potassium chloride, and ammonium salts as sources of nutrients in the fertilizer. The technical result is providing enhanced properties of NPK-fertilizer, in particular a method for its preparation allows to improve the strength of granules, to solve the problem related to the plasticity of granulated complex fertilizers, to improve water solubility of phosphorus contained in the fertilizer by 98%, thereby improving consumer properties of NPK-fertilizer.
(FR) La présente invention concerne un engrais NPK, azote-phosphore-potassium, complexe, dans lequel la fraction massique de l'azote total est comprise entre 13 et 15 %, la fraction massique des phosphates totaux, en termes de P2O5, est comprise entre 11 et 15 %, la fraction massique de potassium, en termes de K2O, est comprise entre 7 et 8 %, ainsi qu'un procédé de préparation dudit engrais à partir d'un sel de phosphate solide, qui est un mélange de fluorapatite Ca5(PO4)3F et de phosphate dicalcique CaHPO4nH2O, n étant compris entre 0 et 2, avec une teneur en fluorapatite Cas(PO4)3F comprise entre 27 % et 99 %, en utilisant divers sels de potassium, en particulier du chlorure de potassium, et sels d'ammonium, en tant que sources de nutriments dans l'engrais. Le résultat technique est de conférer des propriétés améliorées d'engrais NPK, en particulier un procédé pour sa préparation permet d'améliorer la robustesse des granules, pour résoudre le problème lié à la plasticité des engrais complexes granulés, d'améliorer la solubilité dans l'eau du phosphore contenu dans l'engrais de 98 %, ce qui améliore les propriétés de consommation de l'engrais NPK.
